To all whom 'it may concern:

Be it known that I, LEoNoE P. L. 13am, citizen of France, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new andmseful Improvement in Steam-Regenerative Apparatus, of which the following is a full, clear, concise, and exact descriptlon', reference beifig had to the accompanying drawings, for 151g a part of this specification. I j

My invention relates to steam I regenerative apparatus and has for its object the provision ofmeans adapted to regulate the pressure of a flux of steam.

My invention is especiallywell adapted to regulate the fluctuations in pressure in the exhaust of steam engines.

My invention also provides means whereby the steam undergoing treatment is heated. I will explain my invention more fully by reference to the accompan ing drawing, showing the preferred embo iment thereof, the drawing showing as much of the apparatus as is necessary'to understand one embodiment of my invention.

'I' have indicated a vessel a, which, if desired, may be closed, exce t for the steam openings and the safety va V0 6, exhaust, or other steam, undergoing treatment passing from the pipe 0 into the piping d, this piping (1 terminating in aperforated portion that pro'ects into the liquid e, preferably water. me suitable agency 1s employed for superheating the steam that is to be regenerated, this su er-heating agency being comprising, in theembodiment'of the invention shown, a drum containing plates g through whic tubes 9 extend, soth'at the spaces between the end walls of the drum and the plates 9% are adapted to receive on y the steam that IS to under 0' treatment. The spaces between the tu es gr communicate and all of the spaces between the tubes are in communicatlon with piping k, that may lead hot air or other heating fluid throughthe spaces between the tubes 9 so that the steam that is passing through said tubes may be subject to a heating action. The volume ofheating fluid gaseing'through the pi ing it is reignltitedfy nieanstiof valve ntilelc zn sm, so at e, hem ac on upon e owing steam beflgnlated,

Specification of Letters Patent.

Patented June 22, 1909.

The valve mechanism 2' is desirably automatically operated, to which end I employ.

a float 70, carried upon a bell crank Z, which is pivoted at its elbow and which has one of its arms connected with the stem m of the valvefi by a link 'n,-the whole construction being such that when the level of the liquid 6 occu ies a predetermined lowermostposition, t e valve'z' is closed, so that the incoming steam is subject to no heating action, andwhereby as the devel Itihe liquid 6 rises, the valve is opened unt' a point is reached where the super-heating action upon the incoming steam 1s of such a degree that the vaporizing influence of the steam admitted to the vessel axis sufiiciently increased to prevent the liquid frorfi rising higher. I a so preferably employ a super heatin agency for the steam after'it has issued from the vessel a, this super heating agency being indicated at 0. i

As the structural characteristics of the super-heater at 0 are similar to the structural characteristics of the super-heater. indicated at g, I will not give a urther description of the super-heater at o, as it will sufiice to say thatpi iing p is employed for conveying hot air on other'hot fluid throu h the spaces that intervene between the tu es of t e corresponding superheater, the discharged steam finding assage through the piping through the tu ing of the heater 0, to there y be subject to su erheating action.

Valve mechanism 7' is emp oyed for regulatin the action at the super-heater 0, this va ve being located in the piping p and also being desirably automatically operated, to

which end, if desired, the float mechanism is, Z may be employed, the stem of the valve 1 being united with the u per arm of the bell crank Z by means of a link s, so that as the level of the liquid 6 lowers, the valve 0' opens; to permit an increase of the heating action at 0, and asthe level rises, to decreasethe heating actionat 0, the heating action being pre erably totally eliminated when the liquid e reaches an u r predetermined level and being preferably increased most when the liquid 6 reaches a lower predetermined level. I

It will be seen that the super-heater con: trolling devices 2' and were subject to the same regulating influence exerted by the liquid e to o erate as specified and to produce the resu ts desired. 1 Whil I preferthe regulating devices indicated at i and 1' and the governing mechan- 5 ism indicated at is and I, I do not wish to be limited to these characteristics.

If desired, the heating fluid may be re c'eived froma common source with which communication is. afl'orded'by means of a to common (pipe at communicating with the pipin h an p. I

ile I have herein shown the preferred method of regulating the super-heatin action u on the incoming steam as wel as upon t e outgoing steam, I do. not wish to be limited to the precise mechanism illustrated.

I prefer to employ two ,superheflin'g devices, one operating upon the steam after it is discharged and the other operating upon the steam before it is admitted into the interior of the steam regenerating vessel, but I do not wish to be limited in all embodimerits oitheinvention to the use of both an erheating devices. a

t frequently happens that a portion or even the totality. of the steam flowing toward vessel a need not be forced through the-liquid heat retainer contained in the regenerating vessel. Pipe it connected to dome or duct a: by-passes the steam through pipe q above the liquid level, dome or duct :0, allowing the steam flowing through pipe u to flow toward the heat retainercontained I 36 in regenerating vessel ai'if the temperature inthe vessel a is lower t mm the temperature corresponding to the steam pressureof the steam flowing through pipe u. Dome or duct w will also'allow the steam to flow from 40 pi e u to pipe q if the temperature in the vessea is hlgher than thecorresponding temperature of the steam flowing through pipe u. It will be seen that the above described equipment provides for means allowing the fluxf steam to be treated to flow through the steam pipe u, and that the regenerative action of the eat retainer'ewill take effect only when needed; 71. e., that. the flux. of steam will flow to or from the regenera-v tive vessel under the action of difference. in

temperatures, a passage or communication being provided by dome or duct 0: between the steam piping and the regenerative vessel; The steam regenerating vesseldescribed has the characteristic-feature of reversing the direction of the flow of steam in duct 0;. In order that the by-pass a may be thrown totally out of service, or may be adjusted as to its capacity, I employ a hand valve '0 V 60 therein.

In order that there may be an automatic I control of the steam flowing through the bypass when saidby-pass is brought into the duct, the direction. of the flow being generated steam and also the pressure of the incoming exhaust steam, this valve being loaded as desired, so that. when the exhaust steam exceeds a predetermined pressure, said valve is automatically opened to permit the exhaust steam to flow directly through the by-pass 14 into the piping By; means of these valves 1 can prevent t e flux of steam, or part of the flux of steam, fiowin toward vesseli a, from going through su merged 1P8 i Y p I have herein shown and particularly described the preferred embodiment of my invention, but I dov not wish to be limited to the precise details 'of'construction and arrangement of apparatus shown, but,

Having thus described my invention, I claim as new and desire to secure by Letters- Patent q l. A steam regenerative apparatus including a vessel havin a heat retaining body of liquid therein, said vessel serving to receive the steam that is to her erated; and means governed by the liquid' for heating the steam to be treated, said heating means cting upon the steam beforeit interacts with the liquid within the vessel.
